What proportion of pizza restaurants that are primarily for walk-in business have a salad bar? Suppose that, in an effort to determine this figure, a random sample of 1,250 of these restaurants across the United States based on the Yellow Pages is called. If 997 of the restaurants sampled have a salad bar, what is the 98% confidence interval for the population proportion? (Round the answers to 3 decimal places.) sps Appendix A Statistical Tables
